Subject: Make VACUUM accept 1 and 0 as a boolean value.
X-Git-Tag: REL_12_BETA1~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fc7c281f87467c1ff24fd72e0cc313dd6a71873f;p=postgresql

Make VACUUM accept 1 and 0 as a boolean value.

Commit 41b54ba78e allowed existing VACUUM options to take a boolean
argument. It's documented that valid boolean values that VACUUM can
accept are true, false, on, off, 1, and 0. But previously the parser
failed to accept 1 and 0 as a boolean value in VACUUM syntax because
of a lack of NumericOnly clause for vac_analyze_option_arg in gram.y.

This commit adds such NumericOnly clause so that VACUUM options
can take also 1 and 0 as a boolean value.
